PLAlTlNG -MACHINE.

SPECIFICATION forming part of Letters Patent No. 420,382, dated January28, 1890.

Application filed January 18, 1889' Serial Not 296,786. (Modell) To allwhom it may concern:

Be it known that I, CHARLES M. HINE, of New York, county of New York,State of New York, temporarily residing in the city of Pittsburg, Stateof Pennsylvania, have invented a new and useful Improvement in Plaiting-Machines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being hadto the accompanying drawing, which form part of this specification.

My invention relates to an improvement in plaiting-machines, and whichis intended as an improvement upon my application, Serial No. 290,049,filed November 5, 1888; and it consists in the combination andarrangement of parts, to be more fully described hereinafter, andparticularly pointed outin'the claims.

The object of my invention is to furnish a very durable and stableplait-ing-machine, which is simple in construction, and which admits ofthe quick and easy adjustment of the plaiting-blades, the regulating ofthe length or distance of their movement, and also for their removal forthe purpose of sharpening their teeth, or for replacing with blades of adifferent width, or with a difierent kind of blade.

The accompanying drawing represents a perspective of my inventioncomplete.

A represents the frame of the machine. To the bed thereof in the rear ofthe needle-bar is secured the plaiter-frame B, which is either anintegral part of the machine-frame or may be a separate frame, and thensecured to the machine-frame in any suitable manner that may be mostappropriate. Secured to the vertical arm of the machine-frame is a rearbracket 0, and to the front end of the horizontal arm of themachine-frame is abracket D, in which is j ournaled the horizontalplaiteroperating shaft E.

F indicates the driving-pulley, that is rigidly secured to the rear endof theneedledriving shaft G, which is provided with a crank H, both ofwhich are shown. in dotted lines.

Fastened to the rear end of the plaiterdriving shaft is anupwardly-extending slotted arm I, to which the outer end of theconnecting-pitman J is secured, while the opposite end of said pitman isjournaled upon of the plaiter-driving shaft E is a cam L,

which is provided with a collar M, through which passes a set-screw forsecurely fastening it to said shaft. The end of the shaft E passesthrough the cam L sufficiently far to receive a second cam N, which isprovided with a circular slot 0, through which passes the screw P, bymeans of which said cam is secured to the camL and rigidly held in anydesired relation to the cam L. The front the projections b, betweenwhich the upper ends of the operz'iting-levers R are pivoted. Theselevers are provided with hardened bearing-surfaces S, against which thecamsL bracket D is provided with a slot formed by N bear, for thepurpose of moving the said levers inward.

Moving in suitable bearings or openings formed in the plaiter-frame Bare the sliding rods or bars T, to which are secured the adjustablesockets U V, to which are loosely connected the lower ends of theoperatinglevers B, respectively. The sockets are secured to the slidingbars by means of setscrews, which enable their free and ready adjustmentin relation to each other, thus 0 regulating the relative position ofthe plaiterblades in relation to each other and in relation to thepresser-bar, as will be seen from the description hereinafter given.Extending upward from the socket U is a guiding arm or projection. TV,which slides in the vertical groove X, made in the front port-ion of theplaiter-frame, and extending horizontally outward from the socket V isthe guidingarm Z, which has its outer end engaging the after they havebeen pushed inward by the cams, the springs D are provided, which havetheir upper central portions formed into coils, as shown, and theirlower ends secured, respectively, to the frame and to the sockets.

Socketed upon and adjustably secured to the outer ends of the slidingrods outside of the frame B are the hangers E, to which are rigidlysecured the plaiter-blades F.

For the purpose of preventing the plaiterdriving shaft from turningbackward from the pressure of the spring-actuated levers against thecams which operate them, the brake G is provided. This brake has itsinner end pivoted to the side of the bracket 0, and its outer endprovided with an opening which surrounds the operating-shaft. The outerside of this opening is provided with a slit, and the brake is split fora suitable distance below the opening. Passing through the brake is aclamping-screw, as shown, for the purpose of causing the brake to clampthe shaft to any desired extent, and thus prevent it from turningbackward.

I here show only one form of cams; but it will be readily understoodthat any form of cam may be used having any peculiar form or shape, oras many cams as desired, without departing from the spirit of myinvention, and I do not therefore limit myself in;

frame by means of a socket and screw,wherethis respect.

From the above description it will be seen that a construction isproduced which enables the plaiter-blades to be adjusted or removed, themovement of the sliding bars and levers limited, and the number of timesthat the levers shall be operated to each revolution of the shaft Eregulated by making the cams removable, as here shown, and thisadjustment of any part accomplished independent of any other part,whereby the relative position of the plaiter-blades are adjusted and therelative position of the plaiter-bars to the presser-bar regulated.

Having thus described my invention, I claim- 1. The combinatiomwith asewing-machine, of aplaiter-frame placed thereon having verticalportions provided with rodbearings and guideways which extend in a lineparallel with the feed of the machine, and sliding rods provided withplaiter-blades which move in a line parallel with the feed of themachine, guidingarms extending from the rods into the guideways forpreventing them from turning, and a mechanism operated by the machinefor reciprocating the said rods, substantially as described.

2. The combination, with the plaiter-frame provided with guideways androd-bearings, of the sliding rods carrying plaiter-blades,operating-levers, sockets adjustably secured to the said rods, havingguiding-arms which engage the said guideways, and arms to which thelower ends of the operating-levers are connected, substantially asshown.

3. The combination, with the plaiter-framc having guideways androd-bearings, of the sliding rods carrying plaiter-blades, the socketsadjustably secured thereto having an arm engaging the guideways and anarm for the operating-levers, the operating-levers pivoted at theirupper ends and having their lower ends connected to the said sockets,the driving-shaft, and the cams secured thereto which engage the saidlevers, substantially as specified.

4. The combination, with the plaiter-frame provided with guideways androd-bearings, of the sliding rods carrying plaiter-blades, socketssecured thereto having guide-arms, the operating-levers pivoted at theirupper ends and connected loosely at their lower ends to the sockets, thedriving-shaft, the cams thereon engaging the operating-levers, and thesprings which engage the said frame and arms for returning the arms toposition, substantially as shown.

5. The combination, with the plaiter-frame having rod-bearings, of therods, sliding adjustable sockets placed thereon, the operating-leverspivoted at their upper ends and loosely connected at their lower ends tothe said sockets, the operating-shaft, the cams, and the hangerscarrying the plaiter-blades, which are secured to the rods outside ofthe by they can be adjusted and removed, substantially as set forth.

6. The combination of the plaiter-frame, the rods sliding thereincarrying plaiterblades, the sockets secured thereto, means forreciprocating the sockets, and stop rods or bars adjustably secured tothe frame and which are engaged by the sockets for limiting theirmovement, substantially as specified.

7. In a platter, the combination, with the frame, of the sliding rodscarrying the plaiterblades, the operating-levers, the operatingshaft,and the two cams, one secured to the shaft and the other provided with aslot and secured to the other cam by means of a screw, whereby it isadjusted in relation to the other, for the purpose described.
